The invention discloses a channel measuring method and a device, belonging to the field of wireless communication. The method includes: determining the measurement bandwidth of the terminal the size and position of the system bandwidth; according to the measurement bandwidth determined subband size and / or sub sets the number / size; will determine the measurement bandwidth in size and bandwidth of the subband location, size and / or set the number of sub bands / size, is sent to the terminal; receiving terminal return measurement results, measurement results were obtained for measurement of measurement bandwidth corresponding to the size and location of the terminal; terminal measurement results in measuring the size and location of the bandwidth corresponding to the size of the corresponding subband in the measured; or the size of the corresponding sub the terminal in the corresponding position and size of the measurement bandwidth of the corresponding number / size of sub-band with measured results obtained by measurement. The method of the invention avoids invalid feedback and improves the validity and accuracy of channel measurement and feedback.
